Dear list,

I am trying to install Rmpi package in a Windows 7 64 bits laptop following
Dr. Hao Yu's instructions:
http://www.stats.uwo.ca/faculty/yu/Rmpi/windows.htm.I have successfully
accomplished steps 1, 2 and 3 and I can see my host in green color in
wmpiconfig.exe (signal that MPICH2 is running properly). But in step 4,
after installing Rmpi package, when I try to run*
*

> library(Rmpi)
> mpi.spawn.Rslaves()
> mpi.parReplicate(20, mean(rnorm(1000000)))
> mpi.close.Rslaves()


R can not spawn the slaves and freezes, while the cpu usage raises to 100%
with 8 Rterm.exe process running. So maybe the problem is the R
communication with MPICH2 due to some kind of permissions... I am using
MPICH2 1.4 32 bits and tried R 2.11.1 (32bit) and R 2.12.0 (32bit) with Rmpi
5-9 and 6-0 with no results.

Has anyone an idea of what is going wrong?

Some useful information:
